12.0 Status & Control Registers
(Continued)
12.28 DETECT CONFIGURATION REGISTER
This register is used to control the headset detection system.
TABLE 29. DETECT (0x17h)
Bits
0
Field
DET_INT
Description
If set an IRQ is raised when a change is detected in the headset status. Clearing this bit will clear
an IRQ that has been triggered by the headset detect.
If set an IRQ is raised when the headset button is pressed. Clearing this bit will clear an IRQ that
has been triggered by a button event.
If set an IRQ is raised during a temperature event. If cleared, the LM4935 will still automatically
cycle the power amplifiers off if the internal temperature is too high. This bit should not be set
whenever the loudspeaker amplifier is turned on. Clearing this bit will clear an IRQ that has been
triggered by a temperature event.
Sets the time used for debouncing the analog signals from the detection inputs used to sense the
insertion/removal of a headset.
